Key Recovery Systems As stated before the sense of cryptography is a properly designed cryptosystem making it essentially impossible to recover encrypted data without any knowledge of the used key. The issue of lost keys and the being-locked-out from one's own data as a consequence favors key recovery systems. On the other hand the counter argument is confidentiality: as soon as a possibility to recover a key is provided, the chances for abuses grow. Finally it is the state that does not want to provide too much secrecy. On the contrary. During the last 20 years endless discussions about the state's necessity and right to restrict private cryptography have taken place, as the governments rarely care for the benefit of private users if they believe in catching essential informations about any kind of enemy, hence looking for unrestricted access to all keys. The list of "key recovery," "key escrow," and "trusted third-party" as encryption requirements, suggested by governmental agencies, covers all the latest developments and inventions in digital technology. At the same time the NSA, one of the world's most advanced and most secret enterprises for cryptography, worked hard in getting laws through to forbid the private use of strong encryption in one way or the other. Still, it is also organizations like this one that have to admit that key recovery systems are not without any weaknesses, as the U.S. Escrowed Encryption Standard, the basis for the famous and controversially discussed Clipper Chip, showed. The reason for those weaknesses is the high complexity of those systems. Another aspect is that key recovery systems are more expensive and certainly much less secure than other systems. So, why should anyone use them? In that context, one has to understand the legal framework for the use of cryptography, a strict framework in fact, being in high contradiction to the globalised flow of communication. |

Late 1970s - Present: Fourth Generation Computers Following the invention of the first Also, ensuing the introduction of the minicomputer in the mid 1970s by the early 1980s a market for personal computers (PC) was established. As computers had become easier to use and cheaper they were no longer mainly utilized in offices and manufacturing, but also by the average consumer. Therefore the number of personal computers in use more than doubled from 2 million in 1981 to 5.5 million in 1982. Ten years later, 65 million PCs were being used. Further developments included the creation of mobile computers (laptops and palmtops) and especially networking technology. While mainframes shared time with many terminals for many applications, networking allowed individual computers to form electronic co-operations. |

Introduction Political and economic agendas change. People leave, get exchanged. Whereas one of the things that never seem to change is disinformation. Watching different kinds of cultures and regimes throughout history you will always find disinformation. Its use is variable just like its tools. First of all it does not necessarily need words. It is possible to disinform in any kind of language (sounds, symbols, letters or with the help of the body). As it seems to have come into existence together with human communication, we need not even hope that it will disappear once in a while. One could rather say: disinformation has always been there. Instead of hoping to stop it we need to learn to live with it, detect it, restore it to consciousness. Even this will not be any insurance for not walking into the trap. It is an attempt, nothing else. For detecting disinformation one needs to know what types of disinformation are possible and how they work. This site gives you some ideas about the history, tendencies and different types of disinformation, with the restriction that it will mostly be about the Western types of disinformation, as it is still harder to understand the media of disinformation in other cultures; and anyhow, many methods and tools run parallel in different cultures. |

World War I ... With World War I an entire system of ideas how wars work collapsed. Suddenly it was no longer mostly soldiers who had to fight. War became an engagement of every day's life. Everybody got involved. Propaganda therefore changed as well. The campaigns were no longer temporarily and recent but had to be planned for years. Who failed in organizing it or used the wrong keywords failed. Masters of modern propaganda became the British, whereas the Germans failed completely in the beginning. |

blowfish encryption algorithm Blowfish is a symmetric key block cipher that can vary its length. The idea behind is a simple design to make the system faster than others. |

IDEA IDEA is another symmetric-key system. It is a block cipher, operating on 64-bit plaintext blocks, having a key-length of 128 bits. |

The World Wide Web History Project The ongoing World Wide Web History Project was established to record and publish the history of the World Wide Web and its roots in hypermedia and networking. As primary research methods are used archival research and the analysis of interviews and talks with pioneers of the http://www.webhistory.org/home.html |

CNN CNN is a U.S.-TV-enterprise, probably the world's most famous one. Its name has become the symbol for the mass-media, but also the symbol of a power that can decide which news are important for the world and which are not worth talking about. Every message that is published on CNN goes around the world. The Gulf War has been the best example for this until now, when a CNN-reporter was the one person to do the countdown to a war. The moments when he stood on the roof of a hotel in Baghdad and green flashes surrounded him, went around the world. |
